“…The same remarks was obtained with XRD results. Furthermore, it is interesting to point out that the prepared MCC samples have relatively similar average diameters as those obtained in the literature for alfa fibers, reeds, algae and commercial MCC [2,65].…”

Esparto grass, known as alfa, is a renewable biomass widely distributed in southern and western Mediterranean basin. The present work focused on the isolation of pure cellulose from alfa stems, via different approaches, i.e., acidified sodium chlorite (NaClO 2), totally chlorine free (TCF) or their combination, followed by the preparation of microcrystalline cellulose (MCC) using acid hydrolysis method. The obtained samples were characterized using infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetry (TGA) and differential scanning calorimeter (DSC). The FTIR spectroscopy exhibited the removal of lignin and hemicellulose after the delignification and alkaline treatments. The XRD data showed that all of the MCCs have higher crystallinity indexes (Alfa-MCC 73-82%) and belong to cellulose I type. From SEM images, it is clear that the different MCC particles presented rough surface and micro-sized particles. The DSC/ TGA analyses revealed that MCC samples present better thermal stability than their respective cellulose ones, with higher temperature of decomposition (more than 350 °C). Moreover, the use of a combined process yields to MCC with higher crystallinity and better thermal stability. Consequently, based on these findings, the delignification with combined method can be considered as a promising approach to extract MCC from alfa fibers with outstanding features.

“…However, MCCN2 revealed a high mean diameter of 16.56 ± 0.80 µm, which was probably attributed to the difference of the origin of cellulosic sources. [25,26] Additionally, it is found that the mean fiber length of MCCN1 (68 ± 1 µm) is comparable to that of MCCN2 (66.80 ± 0.90 µm), which is an indication that no variation of particle size occurred after the nitration process of MCCs precursor. Indeed, it was reported by Nikolsky et al that the shortness of cellulose fibers plays a key role in the effectiveness of the nitration process.…”

“…As shown in Table , comparable average diameters of 9.60 ± 0.50 µm and 10.60 ± 0.80 µm were found for NC2 and MCCN1, respectively. However, MCCN2 revealed a high mean diameter of 16.56 ± 0.80 µm, which was probably attributed to the difference of the origin of cellulosic sources . Additionally, it is found that the mean fiber length of MCCN1 (68 ± 1 µm) is comparable to that of MCCN2 (66.80 ± 0.90 µm), which is an indication that no variation of particle size occurred after the nitration process of MCCs precursor.…”

“…The presence of more crystalline order in MCCN samples, as illustrated in Figure 2d, can be revealed by the increase of the crystalline band intensity at 1430-1380 cm −1 , and the shift of the CH elongation vibration from 2901cm −1 to higher wavenumber value (2905 cm −1 ). [25,26] According to these results, it can be concluded that the NC2 and MCCN1 synthesized from cellulose and microcrystalline cellulose isolated from marine POBA, respectively, were of high purity, comparable to NC1 prepared from cotton cellulose and MCCN2 produced from C-MCC. Besides that, it is worthy to note that the FTIR spectra of the produced cellulose nitrate and MCCN are comparable with those reported in the literature.…”

“…According to the literature, the use of cellulose as polymer precursor to produce energetic materials instead of other thermoplastic elastomer is due to its potential benefits like the easy and cheap availability, non‐toxicity, biodegradability, renewability as well as the great oxygen amount . Furthermore, it is well known that cotton and wood are the most commonly used raw materials to obtain cellulose precursor . Whereas, these sources are widely used in other fields, such as building products, fabrication of pulp, and textile industry, which pushed the scientific community to explore alternative sources of cellulosic fibers based on non‐wood species like aquatic plants, grass, agricultural residues, and their by‐products.…”

In this study, microcrystalline cellulose nitrate (MCCN) as energetic polymer is successfully obtained from Posidonia oceanica brown algae (POBA). Fourier transform infrared spectroscopy (FTIR) results show alterations in the intensities of some absorption bands, suggesting a significant difference in the chemical structure between microcrystalline cellulose and the emergent MCCN samples. X‐ray diffraction (XRD) measurements indicate that MCCNs are more crystalline than conventional nitrocellulose (NC). According to scanning electron microscopy (SEM), both NC and MCCN reveal a compact structure and a rough surface. Differential scanning calorimetry (DSC) displays that the thermal degradation of MCCNs shifts to lower temperatures compared to the respective NCs. Furthermore, in comparison with NC samples, MCCN samples exhibit high density, high nitrogen content, low viscosity‐average molecular weight, and good thermal stability. On the other hand, kinetic modeling based on DSC data is carried out by isoconversional integral methods to determine Arrhenius parameters and the decomposition mechanisms. It is found that MCCNs present lower activation energies than conventional NCs with a decrease of ≈6%. Finally, this work opens a new pathway to prepare MCCN from POBA, and it is expected to have applications in several areas such as propellants, energetic binders, and gas generators.
